PAUL CAMPBELL, or NEWARK, NEW JERsEY.

To all whom it may concern:

Be it known that I, PAUL CAMPBELL, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Ad vertising Devices, ofwhich the following is a specification.

This invention relates to an advertising device, and more particularly to a device which is adapted to be located in a store or shop window, whereby when operated, the

attention of passers-by will-be attracted to said device, and to the article or articles it is desired to advertise. I

More particularly my invention contemplates the provision in an advertising device of an artificial spark plug of such construction that when operated sparks will be thrown from the parts thereof, in simulation of the actual operation of a spark plug inservice within the 1 cylinder of a gas engine.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations,

arrangements of parts and applications of principles, constituting the invention and the scope, of protection contemplatedwlll be indicated in the appended claims.

In the accompanying drawings, wherein I have shown a preferred embodiment of my invention: 1

Figure l is a view in elevation of my improved advertising device, showing the same as it appears when in operation. 1

Fig. 2 is a vertical cross sectionalview of the upper portion ofthe apparatus.

Fig. 3 is a vertical cross-sectional view of the device showing the means for forming the sparks.

Fig. 4 is a similar view taken at right angles to Fig. 3, on the line Fig. 5 is a cross-sect1onal view taken on line 55 of Fig. 4, looking in the direction of the arrow; and

Fig. 6 is an elevatio-nal view, partly in section, showing a detail of construction.

Referring now to the drawings, wherein similar reference characters refer to similar parts throughout the several views thereof, the reference numeral 1 denotes a structure which is constructed in simulation of a spark plug, and in actual use this device is Specification of Letters Patent.

of a considerable size and is mounted in an inverted position upon a support 2. The device is ordinarily made of wood and is formed in two parts 3 and 4, fitted together at 5 with a sliding fit, so that when the part 2 is moved the interior mechanism will be exposed. This mechanism comprises an electric motor 6, which is connected by a source of current supply, as by means of the cables 7. This motor is supported upon a platform .8 formed interiorly of the part 4 of the device. The reference numeral 9 denotes a bracket supported on the upper end of the part 4 of the device, and journaled in the upper ends of arm 10 and 11, carried upon the bracket 9 is a wheel 12 formed of a considerable abra-dant, such as carborundum or emery. The shaft 13 of the wheel 12 is provided with a pulley 14 adapted to be driven by a belt 15 from the pulley 16 fastened upon the shaft of the motor 6.

Cooperating with the 'abradant wheel 12 is a piece of metal 17 pivotally mounted upon a pin 18 and spring pressed into engagement with theperiphery of the wheel 12, as by means of the spring 19. This strip of metal 17 is removably mounted upon the pin 18,.and it may be replaced by a fresh piece when it has been worn away by the action of the abradant.

The reference numerals 20 and 21 denote pairs of wires which are disposed transversely of the upper end of the part 3, leaving a rectangular space between them, said wires adapted to support, in the position shown, an inverted hollow cone-shaped member 22, which is provided with grooves into which the wires 21 and 22 are received and whereby they are held in the position shown. The upper end 23 of the part 3 is intended to represent one electrode of a spark plug, and the edge 24 of the coneshaped member 23 the other electrode, that is, it is intended that simulation of sparking shall take place between said upper edge .23 and the periphery 24 of said cone-shaped therewith of the metal strip 17, sparks will be produced through the heating by friction of the small metal particles and these sparks will be deflected upwardly and outwardly by the cone-shaped member 22, so that they will be projected through the space provided between the edges 23 and at. These projected sparks are intended to illustrate the operation of a spark plug of this character in actual use. The purpose of constructing the lower end of the coneshaped member 22 as shown, is to facilitate the even distribution of the sparks as they are produced by the action of the abradant Wheel 12 and the steel strip 17, whereby they will be distributed in equal proportions entirely around the spaced edges 23 and 24:.

It will accordingly be seen that I have provided a construction Well adapted to attain, among others, all the aims and objects above pointed out, in an exceedingly simple and efiicient manner. It will be understood that while the cone-shaped member 22 is employed to simulate one electrode, this part may be omitted and the sparks projected directly upward through the opening in the upper end of the member 3.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A device of the class described, a hollow body formed to simulate a spark plug, said hollow body having an open upper end, and means located within the same adapted to project sparks through the upper open end thereof.

2. In apparatus of the class described, in combination, a hollow body constructed in simulation of a spark plug mounted upon a suitable support, means for producing a series of sparks within the same and projecting them upwardly through said open end of said body and means for. driving said spark producing means.

3. In apparatus of the class described, a hollow body formed to simulate a spark plug, said hollow body having an open upper end, mechanical means located therein for producing sparks and projecting them upwardly through said body, and a deflector located upon said body in such position as to guide and deflect the sparks upwardly and outwardly.

at. In apparatus'of the class described, a hollow body formed to simulate a spark plug, said hollow body havingan open upper end, an abradant wheel located therein, means for driving said wheel, means for maintaining a piece of metal in contact with said abradant wheel, and in such posi tion that the sparks formed by the action of the abradant and metallic strip will cause sparks to project upwardly and outwardly through said body. I

5. In apparatus of the class described, in combination, a hollow body formed to simulate a spark plug, said hollow body having an open upper end, an abradant wheel located therein, means for driving said wheel, means for maintaining a piece of metal in contact with said abradant wheel, and in such position that the sparks formed by the action of the abradant and metallic strip will cause sparks to project upwardly and outwardly through said body, and a deflector located within said body and spaced therefrom, adapted to direct sparks up- Y wardly and outwardly between the same and the upper end of said body.

6. A device of the class described, a hollow body formed to simulate a spark plug, and mechanical means located within the same adapted to project sparks through the upper open end thereof.

In testimony whereof I afliX my signature in the presence of two witnesses.
